Indexing is the process by which search engines (Google, Yandex, and others) crawl, analyze, and add a web page to their database. If a page is not indexed, it will never appear in search results, even if its content perfectly matches a user's query. That is why checking indexation is a foundational step in any SEO audit. Pages can fall out of the index for many reasons: robots.txt rules, a noindex meta tag, canonical issues, or simply slow loading.
Our tool quickly shows how many pages of your site are currently held in the Google and Yandex indexes. Just enter a domain to get the current count from both search engines at once. Compare that number with the real size of your site: if the index holds noticeably fewer pages than you publish, part of your content is not reaching search at all. Detecting and fixing indexation problems in time is a direct path to increasing organic traffic and visibility in search.
